Skywire Package Installation

Installing Skywire as a Package

Using a package of skywire allows the package manager to handle the installation and updates.

Debian-based systems ( Debian / Armbian / Raspbian / *buntu )

Skywire is available to install as a package from the apt repo at https://deb.skywire.skycoin.com using the apt command on .deb based linux distros

Configuring the package repository allows the package to be updated with the rest of the software installed on the system as new versions become available or revisions to packaging are made (i.e. minor release).

1) Download and install the repository configuration and signing key

Installing the skybian package will allow skywire to be installed or updated with apt

This step only needs to be done once (or on changes to the apt repo location / keys) This has already been done in the new skybian images (1.0.0)

curl https://deb.skywire.skycoin.com/archive/skybian-$(dpkg --print-architecture).deb -o skybian-$(dpkg --print-architecture).deb
sudo dpkg -i skybian-*.deb
rm skybian-*.deb

2) Resync the package database

sudo apt update

3) Install skywire

sudo apt install skywire-bin

Note: if this command is executed in the dmsgpty terminal on versions older than 1.0.0, it is required to include DMSGPTYTERM=1 after sudo & before apt

sudo DMSGPTYTERM=1 apt install skywire-bin

Note: if you want to use keys from a previous config:

• place the config file at /etc/skywire-config.json
• remove the config from /opt/skywire/skywire.json
• then run skywire-autoconfig

Note: The default config from skybian was used automatically

4) Configure Remote hypervisor

Assuming the previous steps have been completed on more than one machine, provide the public key of the hypervisor as an argument to the skywire-autoconfig command

skywire-autoconfig 924b125136a9eeac0ceb079005846e02500d26129e073ef0d913bcd364795e8377

To subsequently reset to a local hypervisor configuration

skywire-autoconfig 0

5) Enable VPN server

The VPN server will be enabled by the skywire-autocofig script if VPNSERVER=1

sudo VPNSERVER=1 skywire-autoconfig

To enable the VPN server persistently via skywire-autoconfig, execute the following commands:

echo "export VPNSERVER=1" | sudo tee -a /etc/profile
source /etc/profile

then log out and log back in

If you run as a regular user (not root) it's also required to execute the following command:

echo 'Defaults env_keep += "VPNSERVER"' | sudo tee -a /etc/sudoers.d/skywire

In this way, the VPN server will be enabled when the config is updated by sudo skywire-autoconfig

and it will not be disabled by updating skywire or re-running sudo skywire-autoconfig as it would have been

6) Updating

Skywire will be updated along with the rest of the software on the system with apt

apt update
apt upgrade

Skywire alone can be explicitly updated with

apt update
apt install skywire

7) Troubleshooting

Almost any issue with configuration should be solved by running:

skywire-autoconfig

The visor or hypervisor should be enabled appropriately with this command. Missing configs will be regenerated.
Helpful text is printed with links to access the hypervisor UI, VPN, as well as links to the uptime tracker and whitelist.
It is safe to re-run this command at any time.

8) Uninstalling

If the above troubleshooting procedure does not work, it may be necessary to uninstall and re-install the package.
Uninstalling can be done with APT:

sudo apt remove skywire-bin

9) Using DPKG

In the instance that the packages fail to download with apt, it is possible to install the package with dpkg
The packages can be manually downloaded from https://176.9.28.105/archive.
Copy the URL of the latest versioned release into the curl command:

sudo curl -L http://176.9.28.105/archive/skywire-bin.deb > skywire-bin.deb

and install with dpkg

sudo dpkg -i skywire-bin.deb

remove or uninstall a package with dpkg

sudo dpkg -r skywire-bin 

10) Automatic Updates

By default, many deb-based linux distros now include the unattended-upgrades package, which can be enabled for use with the apt repository configured in the first step.
If you do not have this package installed, first install unattended-upgrades

apt install unattended-upgrades

Edit the file at /etc/apt/apt.conf.d/50unattended-upgrades

nano /etc/apt/apt.conf.d/50unattended-upgrades

Add the following line at the first blank line (around line 33)

        "origin=skycoin,codename=sid,label=skycoin";

You may wish to uncomment some lines above it as well, this is left to the discretion of the user.
Save and exit the file (ctrl+x type y press return)
Run the following commands as root to enable the automatic updates

echo unattended-upgrades unattended-upgrades/enable_auto_updates boolean true | debconf-set-selections
dpkg-reconfigure -f noninteractive unattended-upgrades

11) Issue Reporting

Issues related to the packaging should be reported in the skycoin/AUR repository

Arch-based systems ( EndeavourOS / Manjaro )

Skywire is available to install from the Arch User Repos (AUR) with tools such as yay or pamac

for the binary release:

yay -S skywire-bin

using the latest source archive:

yay -S skywire

or manually, with makepkg

git clone https://aur.archlinux.org/skywire
cd skywire
makepkg -sif
#or build from cloned git sources
makepkg -sif -p git.PKGBUILD
